DESCRIPTION PREFERRED EMBODIMENTS

FIG. 1 schematically shows a controlling system according to a preferredembodiment of the present invention. Referring to FIG. 1, twocommunication terminals 110 and 120 use, for example, a portablecommunication device 110 or 122 to communicate with each other. In thepresent embodiment, the portable communication devices 112 and 122 maybe mobile phones.

According to an embodiment of the present invention, the communicationterminals 110 and 120 may use a wireless transmission protocol to link,for example, the portable communication device 112 to the portablecommunication device 122. In a preferred embodiment of the presentinvention, the wireless transmission protocol mentioned may be aBluetooth transmission protocol or a wireless local area networkpoint-to-point transmission protocol.

After the communication link between the communication terminals 110 and120 is established, the controlling system detects a plane and aposition on which the portable communication device 112 or 122 islocated and generates a 3-D data. Next, the 3-D data is converted into adata format conforming to the wireless transmission protocol and the 3-Ddata is transmitted from, for example, the portable communication device112 to the portable communication device 122 via the wirelesstransmission protocol. Thereafter the portable communication devices 112and 122 recover the converted 3-D data and generate the respectivecontrol signal according to the 3-D data. Accordingly, the communicationterminals 110 and 120 use the 3-D data to control the correspondingportable communication device to communicate with each other.

FIG. 2 schematically shows a circuit diagram of a portable communicationdevice supporting 3-D detection according to a preferred embodiment ofthe present invention. Referring to FIG. 2, each of the portablecommunication devices 112 and 122 of FIG. 1 comprises a processor 201electrically coupled to a 3-D detector 203 and an antenna 205.

As shown in FIG. 2, it is common that the portable communication devicemay further comprise an input device 207 and a display 209. Wherein, theinput device 207 may be a keyboard or a joystick to serve as a useroperation interface. In addition, the output of the input device 207 iselectrically coupled to the processor 201, and the processor 201controls the display 209 to display the information.

FIG. 3 schematically shows a flow chart illustrating an interactionmethod between two communication terminals according to a preferredembodiment of the present invention. Referring to FIG. 2 and 3, first,at step S301, the processor 201 creates the communication link with theother communication terminal through the antenna 205. Taking theBluetooth transmission protocol as an example, when the communicationterminal 110 establish a communication link with the communicationterminal 120 of FIG. 1, first a SDP protocol is used to query a RFCOMMserver channel number used by the communication terminal 120. Then, thecommunication terminal 110 performs an authentication on thecommunication terminal 120 in order to build up the transmission channelbetween the communication terminal 110 and the communication terminal120.

Next, at step S303, the processor 201 uses the 3-D detector 203 todetect a plane and a position on which the portable communication device(e.g. the portable communication devices 112 and 122) is located and togenerate a 3-D data. After the 3-D data is generated by the processor201, at step S305, the 3-D data is converted into a data formatconforming to the wireless transmission protocol by an applicationprogramming interface (API). Next, at step S307, the processor 201transmits the converted 3-D data to the other communication terminalthrough the transmission channel mentioned above.

FIG. 4 schematically shows a flow chart illustrating the steps when acommunication terminal is receiving the 3-D data from the othercommunication terminal. Referring to FIG. 4, first in step S401, afterthe 3-D data converted at step S305 is received by a communicationterminal through the transmission channel, the received 3-D data isrecovered. Next, at step S405, the communication terminal receiving the3-D data generates a control signal according to the recovered 3-D data,and the operations of the portable communication device in thecommunication terminal are controlled according to the control signal.

In summary, in the present invention, a 3-D data is generated by theportable communication device and transmitted to the other portablecommunication device in a second communication terminal. Thus, aconventional input device may be used to control the operations of theportable communication device in the other communication terminal. Thus,the user can play the on-line game with the other user without using theinput device such as the keyboard or joystick. Thus, the service life ofthe mobile phone and the user need not use the small input device, whichprovides greater convenience and more fun while playing on-line games.
